How we worked it out Updated as you change the numbers.
Amount = 1,000 × (1 + 7%)^10. Doubling time = ln 2 ÷ ln(1 + rate). The rule of 72 (72 ÷ rate %) is a quick approximation. Method and assumptions Discrete compounding once per period. For continuous growth at rate k, use e^(kt), which this matches when the per-period rate is e^k − 1.
Questions What does 1,000 grow to at 7% for 10 periods? 1,967.15. It doubles every 10.24 periods.
